BOTTLING-MACHINE.

Specification of Letters Patent.

Patented Feb. 27, 1912.

Application filed October 31, 1910. Serial No. 590,008.

To all whom t may concern Be it known that I, ANDERS ANDERSENPINDs'roFTn, manufacturer, a citizen of the Kingdom of Denmark, residingat No. 62 Frederiksberg Alle, in the cityof Copenhagen, Denmark, haveinvented certain new and useful Improvements in Bottling-Machines; and Ido hereby declare the following to be a full, clear, and exactdescription of the invent-ion, such as will enable others skilled inthe'art to which it appertains to make and use the same.

This invention relates to improvements in bottling machines, and has forits object to minimize the loss of liquid due to the bursting orbreaking of bottles during the bottling process, and to automaticallycut off the iiow of liquid when filled bottles are moved away from thefilling nozzles.

Another object is to so mount the controlling valves that they maysimultaneously be moved away from their seats when the machine is to becleaned.

vWhile the invention is'not limited to the exact details shown anddescribed, still for the purpose of disclosure reference is had to theaccompanying drawings illustrating means for carrying out the invention,in which drawings like letters designate the same parts in the severalviews, and in which- Figure 1 is a view in vertical section throughparts of a rotary bottling machine embodying the present invention, oneof the bottles being shown as broken to illustrate the automaticoperation of the controlling valve. Fig. 2 is a similar view through astationary bottling machine, and Fig. 3 shows a fragmentary sect-ionalview of modified details.

In carrying out the present invention I provide valves normally held inan open position when the pressure in the discharge end of the bottlingpipes is equal to or greater than the liquid pressure in the fillingtank, and which are automatically closed by the pressure of the liquidcontents of the tank when the pressure in the discharge end of thebottling pipes is reduced, owing to the removal of the bottle beingfilled or owing to its'being broken.

In the construction illustrated in Fig. l, wherein'a rotary bottlingmachine is provided, a designates the liquid reservoir, o bottling4pipes leading therefrom and terminating in discharging nozzles c airpipes terminating adjacent said discharge ends or nozzles b andconnected at .their other ends to an air supply pipe eZ.

c designates one of a plurality of clack valves, one being provided forthe eduction orifice of each bottling pipe, and being so mounted, andits weight so proportioned yor so counterbalanced, that it normally liesin the position shown at the left of Fig. 1.

In the construction shown in Fig. l these valves are movably suspendedon the interior of the liquid reservoir a by a movable support, such asa rotary or tilting ring fn. operated by meansof any suitable angle barm passing through the reservoir and provided with an operating handle,enabling all of the valves to be moved away from their seats at theeduction orifices of the bottling pipes when the bottling machine is tobe cleaned. It is obvious that other suitable means may loe employed for4movably supporting said valves to shift them simultaneously. f y

In Fig. l 7 designates the rotating means for said machine, g thebottles to be lled, and h the operating plungers for forcing the bottleinto operative engagement with the filling means and withdrawing sametherefrom, these features being obvious to those familiar with the art.

In the stationary form of filling means shown in Fig. 2, theconstruction, so far as the present invention is concerned, issubstantially the same, the same parts being designated by the sameletters as in Fig. l. In this view the bottles g are moved by thecarriers i operated by the counterbalancing weights j, all of well knownconstruction.

In the construction shown in Fig. 3 the valves are arranged at rightangles to the position previously described, and instead of beingnormally held open up by gravity are normally held in their openposition by a counterbalancing weight 0, when the liquid pressure is nogreater than the counterpressure in the bottling pipe b.

In operation it will be observed that with the bottle g vin the positionshown to the left in Fig. l and held in cooperative relation with thefilling nozzle, when the pressure in the bottle from the air pipe d isequal or greater than the liquid pressure in the reservoir a, the valvee will be in its normal openV position shown at the left in the figure,being held in said position by gravity when the pressures are equal onboth sides, and when the pressure is greater in the bottle g then bygravity plus the eX- cess pressure. Should the bottle burst, however,the pressure at the discharge end of the pipe will be greatly reduced,and this, together with the tendency to increased velocity in the flowof the liquid, will cause the greater liquid pressure in the reservoir ato immediately close the valve e against its seat, as illustrated at theright in Fig. 1, the same operation following' when the bottle isremoved instead of being broken. It will also be observed that thevarious bottling pipes may be readily cleaned by moving the support n soas to remove the valves e from their seats, as described.

From the foregoing statement of opera- Y tion vthe operation of themodiiied form will be apparent, and it will be seen from this invention'that the waste of the liquid being bottled is minimized, and that alsogreater cleanliness is attained by preventing liquid from being ejectedor spat-tered over apparatus and the bottling department Whenever abottle happens to break.

I-Iaving thus described the invention,what I claim is 1.v In a bottlingmachine, the combination of a liquid-reservoir, bottling pipes leadingfrom said reservoir, an air-reservoir, and

air-pipes leading to said air reservoir, with clack valves or the likeclosing automatically said bottling pipes as soon as the outflow exceedsthe normal, said valves being mounted upon a common support, and meansfor moving said support so much that the valves can be moved out fromtheir operative position, when the machine shall be cleaned.

2. In a bottling machine, the combination of a liquid reservoir,bottling pipes leading from said reservoir, an airA reservoir and airpipes leading to said air reservoir, with weighted or counter balancedclack valves or the like closingautomatically said bottling pipes assoon as the outflow exceeds the normal and arranged in front of each ofthe inner orifices of said bottling pipes, said valves being mountedupon a common support, and means for moving said support so much thatthe valves can be removed from the orifice of the bottling pipes, whenthe machine shall be cleaned.

In testimony whereof, I have aiiiXed my signature, in presence of twowitnesses.
